OTA – These three little words are the essence of free TV. They simply stand for over-the-air which is how free local broadcasting signals are distributed.

UHF – Another OTA frequency, these letters signify the ultra high frequency means of transmitting OTA signals. This frequency is the way the majority of the OTA signals are transmitted from local broadcast towers. Broadcast Tower – Towers are structures where TV and radio signals are produced for the free, general use of the public. To access the signals transmitted equipment, such as a rooftop antenna, are required. Rooftop Antenna – This antenna received the broadcast tower signals and is generally located on a structures roof. However, these types of antennas can also be mounted in attics.
